Answer 1

你可以检查，

[dateFormatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]]; 

代替，

[dateFormatter setTimeZone:[NSTimeZone systemTimeZone]];

Answer 2

我已经修改了@ACB 的代码，因为有一些拼写错误，尝试[dateFormatter setTimezone:[NSTimeZone timeZoneForSecondsFromGMT:0]];而不是[dateFormatter setTimeZone:[NSTimeZone systemTimeZone]];. 这似乎对我有用。

我想将这个答案归功于@ACB。他/她想出了这种技术，我只是确认了它。
